The continual growth in commercial aviation fuels and more strict environmental legislations have led to immense interest in developing green aviation fuels from renewable lignocellulosic biomass. This work demonstrated a novel transformation of biomass into bin-jet and diesel fuels. The transformation included following three reaction steps: (i) the catalytic pyrolysis of sawdust into low-carbon aromatics, (ii) the production of C8-C15 aromatics by the aromatic alkylation and (iii) the production of C8-C15 cyclic alkanes by the hydrogenation of C8-C15 aromatics. The production of the desired C8-C15 aromatics with the highest selectivity of 92.4% was achieved by the low temperature alkylation reactions of the low carbon aromatics using the ionic liquid of [bmim]Cl-2AlCl(3) (1-butyl-3-methylimidazolium chloroaluminate). The biofuels derived from sawdust basically met the main specifications of jet fuels. This transformation potentially provides a useful avenue for the development of green aviation biofuels utilizing lignocellulose biomass. (C) 2015 Elsevier Ltd. All rights reserved.
